Today, almost the whole accelerator complex is operational and providing beams to all the experimental facilities as scheduled. The LHC experiments are taking data, while the LHC is nearing the end of...
2018 SPIE An Optical Believe It or Not:Key Lessons Learned V
2018 SPIE Optical Believe It or Not Key Lessons Learned V
2017/11/27
This conference is dedicated to the sharing of key optical lessons learned. Nearly all optical engineers, scientists, researchers, or managers have dealt with the unexpected. Many of these situations ...
Inverted,but not perfectly:First trace of differences between matter and “ordinary” antimatter
Inverted but not perfectly First trace differences between matter ordinary antimatter

In data collected during the first phase of operation of the Large Hadron Collider the LHCb collaboration team has discovered an interesting asymmetry. The most recent analysis of decays of the beauty...
Cesium atoms shaken, not stirred, to create elusive excitation in superfluid
Cesium atoms shaken not stirred elusive excitation superfluid

Scientists discovered in 1937 that liquid helium-4, when chilled to extremely low temperatures, became a superfluid that could leak through glass, overflow its containers, or eternally gush like ...
Why three-body physics do not solve the proton radius puzzle
proton radius puzzle Atomic Physics
2012/5/28
The possible involvement of weakly bound three-body systems in the muonic hydrogen spectroscopy experiment [1], which could resolve the current discrepancy between determinations of the proton radius,...
Regular $g$-measures are not always Gibbsian
Discrete-time stochastic processes g-measures chains with complete connections non-Gibbsianness chains with variable-length memory
2011/7/28
Abstract: Regular $g$-measures are discrete-time processes determined by conditional expectations with respect to the past. One-dimensional Gibbs measures, on the other hand, are fields determined by ...
It was found recently that tunneling probabilities over a barrier is roughly twice as large as that given by standard WKB formula. Here we explained how this come from and showed that WKB method does ...
We investigate medium effects on mesonic screening lengths for QCD with 2-flavours of dynamical staggered quarks on lattices with cutoff a=1/6T. Denoting the cross-over temperature by $T_c$, we vary t...

2010/11/8
Dynamical A and B maps have been employed extensively by Sudarshan and co-workers to investigate open system evolution of quantum systems. A canonical structure of the A-map is introduced here. It is ...
New Exactly Solvable Two-Dimensional Quantum Model Not Amenable to Separation of Variables
Two-Dimensional Quantum Model Amenable Separation Variables
2010/11/11
The supersymmetric intertwining relations with second order supercharges allow to investigate new two-dimensional model which is not amenable to standard separation of variables. The corresponding po...
Explaining the Unobserved: Why Quantum Mechanics Is Not only About Information
Quantum information Collapse theories Crucial experiments Constructive theories
2011/9/8
A remarkable theorem by Clifton, Bub and Halverson (2003) (CBH) characterizes quantum theory in terms of information--theoretic principles. According to Bub (2004, 2005) the philosophical significance...
In the many worlds community seems to exist a belief that the physics of a quantum theory is completely defined by it's Hamilton operator given in an abstract Hilbert space, especially that the positi...
Controlled-NOT logic with nonresonant Josephson phase qubits
Controlled-NOT logic nonresonant Josephson phase
2010/4/7
We establish theoretical bounds on qubit detuning for high fidelity controlled-NOT logic gate implementations with weakly coupled Josephson phase qubits. It is found that the value of qubit detuning d...
The concept of the half density matrix is proposed. It unifies the quantum states which are described by density matrices and physical processes which are described by completely positive maps. With t...
